CONDENSER.-

SPECIFICATION forming' part of Letters Patent No. 758,090, dated April 26, 1904.

. 3 Application filed May 16, 1903 Serial No. 157,382. (No model.)

- in the German Empire, have invented certain 'newand useful Improvements in or Connected with Jet-Condensers, of which the following is a specification, reference being had to the drawing hereunto annexed, and to the letters marked thereon-that is to say:

This invention has for its object to obtain the best vacuum with a limited quantity of .cooling-water in jet-condensers and also to reduce to a minimum the changes in intensity of the vacuum arising from unequal admission of the exhaust-steam to the condenser sys= tem.

In order to obtainthe above results, I provide two or more jet-condensers of any suit able type arranged in series in such a way that the cooling-water entering one of the condensers, where it is distributed in any of the usual ways, will not be allowed to flow off or be pumped outto the atmosphere, but will be collected in the lower part of said condenser and afterward passed into the next condenser of the series by means of pumps or flow thereinto by gravity, be again distributed and collected, and afterward introduced into the third condenser, if such exist, and so on until after having passed the last condenser in the system it will be allowed to flow off or be pumped out to the atmosphere, while the exhaust-steam is conducted in the opposite direction through the condensers and the vacuum-pump is connected with that condenser into which the water first enters and the exhaust steam terminates its passage through the system.

The invention will be clearly understood from the accompanying drawing, which represents diagrammatically a vertical section of two condensers connected in the way de-- of the barometer type with tail-pipe 0, and (3 represents a second jet-condenser. Water is admitted by a pipe d into the condenser Z2,

where it is sprayed, and it is thenconducted by a pipe c into the condenser a, where it is again sprayed. The cooling-water therefore passes through the condensers in the direction indicated by the arrows marked 1 to 7, while the exhaust-steam is admitted at f to the condenser a, whence it passes through the pipe g into the condenser 5 below the waterspray following the direction of the arrows 8 to 10, and the air separated during the process-of condensation is drawn off at the pipe h in the direction of the arrow 11 by means of a vacuum-pump a; of any suitable kind. a

It will bereadily understood that the exhaust-steam-being first exposed to a spray of warm injection-water and afterward to another spray of cold water will be efficiently condensed and separated from the air mixed with it, the latter following the way of the vapors from a to b, and finally being drawn old in a concentrated and cold state at h. It will also be seen that during periods when little steam enters the condenser a the condensation will in great part be completed in a, while the coolness of the water in b will increase. If, however, either gradually or suddenly a heavier load of exhaust-steam be thrown upon the system, the condenser I) will take a greater share in the condensing action until the volume of exhaust-steam admitted is again reduced. Under these conditions the condenser I) may for the time being do the whole work of condensation, as meanwhile much warmer water than before will have accumulated at the bottom thereof and enter the condenser a, through which it flows without performing any condensing action until after atime the water accumulating in Z) and passing to a becomes cooler again and the original state of the condensing process is reestablished.

The condenser 6 should preferably have a sufficient storage capacity to allow for the periods of heavy steam load, which latter being known the former is a simple matter of calculation.

The arrangement of parts hereinbefore set forth is very convenient when local conditions are to be met or existing single condensing plants extended or combined with a view of obtaining improved efiiciency or larger capacity. I

Having now particularly described and aseertained the nature of the said invention and in What manner the same is to be performed, I declare that I do not claim to have invented a new method of condensing steam, it being known that the steam can be conducted in a direction opposite to that of the condensing- Water with advantage and also that pockets arranged within a condenser or attached to it from the outside and subsequently filled by the injection-water have the efi'ect of equalizing the vacuum under varying admission of steam; but

What I do claim as my invention is 1. In acondensing apparatus, the combination of a plurality of jet-condensers, the first having a steam-inlet opening, and a steamoutlet opening, and the second having a steaminlet opening connected with the steam-outlet opening of the first, a jet. device for connection with a cold-water supply and adapted to deliver a jet into the second condenser, and a jet device connected with the. lower part of said second condenser, and adapted to deliver a jet into the first condenser, said condensers 1 being otherwise unconnected, whereby the water-passes through said condensers but once.

2., In a condensing apparatus, the combination of a plurality of jet-condensers, the first having a steam-inlet opening, and av steam-out let opening, and the second having a steamv inlet opening connected with the steam-outlet opening of the first, a jet device for connection with a cold-water supply, and'adapted to deliver ajet into the second condenser, a jet device connected with the lower part of said second condenser, and adapted to deliver a jet into the first condenser, said condensers being otherwise unconnected, whereby the water passes through said condensers but once, and an airpump connected with said second condenser,

, 3. In a condensing apparatus, the combina I tion of a plurality of jet-condensers arranged in series, each having a stearnfinlet opening, and each having a water-inlet at its upper part and a water-outlet at its lower part, an airpump connected to the last condenser, a jet device for each condenser adapted to discharge into. same above its steam-inlet, a connecting steam-passage between each twojcondensers leading from. the body of the one to the steam- ;inlet of the other, and a connecting waternected except by such two-passages, whereby the condensing-water is used but once. a

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
